Los Angeles: Pop star Beyonce Knowles and husband Jay Z have embarked on a 22-day vegan challenge until Christmas Day.

The 44-year-old rapper and his pop star wife are inspired by a close friend to give up meat and dairy products, reported E! online.

"Psychologists have said it takes 21 days to make or break a habit. On the 22nd day, you`ve found the way. On December 3, one day before my 44th birthday I will embark on a 22 Days challenge to go completely vegan, or as I prefer to call it, plant-based," Jay Z wrote on his blog.

"This all began a few months back when a good friend and vegan challenged me to embrace a `plant-based breakfast` everyday. It was surprisingly easier on me than I thought," he said.

As vegans the couple should also avoid animal-derived garments, including fur, wool and leather, although Beyonce, 32, was spotted wearing wool and leather while visiting a vegan eatery Real Food Daily in West Hollywood this week.
